KILL (Resource kit)
Remove a running process from memory.
Syntax
KILL [option] process_id
KILL [option] task_name
KILL [option] window_title
Option
-f Force process kill
Note: Kill -f basically just nukes the process from existence, potentially leaking a lot of memory and losing any data that the process hadn't committed to disk yet. It is there for worst case scenarios - when you absolutely must end the process now, and don’t care whether proper cleanup gets done or not.
In Windows XP, KILL is replaced with the superior TASKKILL - Allowing you to specify a remote computer, different user account etc - for more details run TASKKILL /?
